摘要： An electrophotographic printing machine in which a developer roller transports a developer material comprising carrier granules and toner particles closely adjacent to an electrostatic latent image recorded on a photoconductive surface so as to develop the latent image with the toner particles. A member is positioned closely adjacent to the developer roller to attract the toner particles to at least one surface thereof. A beam of energy is transmitted through the member onto the surface on which the toner particles adhere. The internal angle of incidence of the beam of energy is greater than the critical angle of incidence of the member. The intensity of the beam of energy internally reflected through the member is detected. A signal indicative of the quantity of toner particles attracted to the surface of the member is generated. The signal is processed and a signal transmitted indicating the end of the useful life of the developer material.

摘要： In an electrophotographic imaging device, in which an electrostatic image is formed and developed on a first support to form a toned image, and the toned image is transferred to a second support substrate and subsequently to a final support, and in which to form color images, a succession of toner images are superposed on each other by transfer from one or more first support to the second support, transfer efficiency is enhanced and color consistency is improved by providing an order of superposition which places the toner having the greatest residual mass/area dependent color instability in a position of being sandwiched between or protected by two or more other toner images whose color contribution to gray balance is not as greatly dependent on mass per unit area. Thus, during transfer, the sandwiched or middle layer(s) will retain integrity.

摘要： In an ionographic device projecting a modulated stream of ions in imagewise fashion towards a moving imaging surface, including an ion printing head having an ion chamber supporting a coronode held at a voltage V.sub.C to produce ions for deposit on an imaging surface and a modulation channel extending from the ion chamber towards the imaging surface through which a stream of ions is directed for imagewise modulation by a plurality of modulation electrodes, electric field distribution within the ion chamber is controlled by selectively varying voltages along the surface regions of the ion chamber to different voltage levels, in an arrangement causing focusing of ion density in the area of the ion chamber adjacent to the modulation channel. An increased ion density in the area of the ion chamber adjacent to the modulation channel assists in providing an increased corona current at the output of the device.

摘要： Apparatus and method for reducing toner contamination in an electrostatographic reproducing machine are described wherein at at least one housing which performs an operation on an imaging surface bearing an electrostatic latent image involving charged toner particles has at least one electrode extending across the width of and spaced from the imaging surface at at least one exit portion through which air normally flows from the housing to other portions of the machine, the electrode being electrically biased to a polarity and magnitude selected relative to the charge on the imaging surface to create an electric field barrier in the exit portion sufficient to repel the charged particles in the exiting air back into the principal portion of the housing substantially without restricting the air flow from the exit portion. In a preferred embodiment the electrode is positioned substantially parallel to the imaging surface. This electrostatic seal arrangement may be used in development or cleaning housings and a preferred mode is used in a magnetic brush development housing at the imaging surface entrance portion where the magnetic brush moves in a direction counter to the direction of the imaging surface.

摘要： A color process in which color copies of an original document containing color information are reproduced. Successive single color electrostatic latent images are developed with particles having a predetermined triboelectric charge thereon. These particles are transferred from the single color electrostatic latent images to a sheet of support material in a prescribed sequence. The sequence of transfer is such that each successive layer of toner particles transferred to the sheet of support material has a lesser triboelectric charge thereon than the preceeding layer transferred thereto. In this manner, back transfer from the sheet of support material to the electrostatic latent image is minimized.

摘要： The undesirable image defect of dragout of liquid ink development (LID) toned images generated from the development zone, formed by an imaging member and a metering/development member, can be prevented. Background development of the toned images is suppressed in an image enhancement zone. With the aid of an enhanced electrostatic field, created by an electrode biased at a voltage other than normal development bias in the metering zone, the toned layer can resist higher viscous forces. Image dragout, due to the viscous shear from liquid ink, can therefore be eliminated.
